Application led January 15`, 1916. Serial No. 72,317.

for one of its objects to improve the con? struction and increase the efficiency and utility and devices of this character.

Another' object of the invention is to provide a simply constructed apparatus which may be adapted without structural change to wagon bodies or boxes of various sizes and to dump loads of various materials from the box.

lVith these and other objects in view, the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims; and in the drawings illustrativel of the .preferred embodiment of the invention' Figure' 1 is a front elevation of the improved apparatus without the wagon body or box; Fig. 2 is aside elevation partly in section of the improved apparatus with .a section of a wagon body and va portion of its running gear in position; Fig. 3 is an enlarged detached perspective view of one of the carrier devices; Fig. 4 is an enlarged detached perspective view of one of the supporting devices; Fig. 5 is an enlarged detail view illustrating the construction of a portion of the supporting mechanism; Fig. 6 is a section ontheline 6 -6 of Fig. 5; Fig. 7 is a section on Athe'line 7 7 of 5.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters. g

The improved apparatus is designed to be arranged in connection with a bin or receptacle for the' products to be dumped, such for instance, as a corn crib or the like, and a portion of the corn crib is illustrated conveniently and comprises a supporting frame including vertical members 10, a floor 11,

and side members 12, the latter being in the form of slats or boards slightly spaced apart to provide for the ventilation of the contents of the bin or crib. A portion of the roof is represented conventionally at 13, these parts being of the usual construction. The front wall of the bin or crib is spaced a considerable distance below the roof portion 13 leaving an open space above the wall members 12 through which the load is dumped. The bottom of the open space is defined by a horizontal plate member, iiidicated at 14. 4The side walls of the crib are supported by a plurality of the frame members 10, and at the front these frame members extend upwardly only to the plate member 14 to which they are attached, as illustrated in Fig. 1.

The improved device is mounted upon two independent frames spaced apart and` attached to the front wall of the crib. Each frame includes vertical members 15 and arranged in pairs. The pairs of frame members 15 are spaced apart and spaced from the ends of the crib, as illustrated in Fig. 1, the distance between the pairs of frame members 15 preferably being less than the distance between the bolsters of an ordinary wagon, but it is not ldesired to limit the distance between the frames. The elevating mechanism is connected rto the frame members 15, as before stated, and as the velevating mechanism connected to these frame members is exactly alike, a description of one will sufiice for both.

Attached to the frame members 15 at their upper ends are bracket devices 16, while similar bracket devices 17 are connected to the frame members about mid-way between the bracket member 16 and the ground v on which thel device is erected. Connected tov each of the bracket members 16 is va vertical member, or support, 18, the latter being spaced apart and extending in parallel relation. At their lower ends the rear edges of the members 18 are inclined to the longitudinal axis of the members 15, as illustrated at 19, while their upper ends are inclined in the reverse order, as illustrated at 20. Attached to the outer faces of the members 18 are metal bearing plates 21, the inner edge of the members 21 overlapping the contiguous faces of the members 18 to form guide tracks, as hereafter explained. At their upper ends the members 21 are inclined to correspond to the inclined face 20 of the members 18 so that the members 21 are inclined inwardly toward the crib, as illustrated at 22. A short shaft 23 is mounted for rotation upon each contiguous pair of bracket members 16 by suitable bearing boxes 24, and mounted upon each of the shafts 23 is a grooved wheel 25, the.

latter being disposed between the inclined portions 22 of the guide plates and the interior of the crib, as shown in Fig. 2.

A portion of the running gear of the kwagon whose load is to be dumped, is indicated at 26, and the box or body at 27, the latter resting in the usual manner upon the bolsters of the running gear and with one edge extendingabove the other edge, as indicated at 28. The member 28 is the usual attachment to vehicles of this character in which the load is deposited from the pile of products in the field, such as for instance corn on the cob, or the like, toV prevent the corn or other product from being thrown over' the opposite edge of the box.

A suitable supporting device is slidably arranged between each of the members 18 and comprises bell-crank shaped members or devices, each including metal side portions 29 spaced apart and an intermediate wood portion 30, the vertical portions extending in front of the contiguous faces of the plates 21, while the horizontal portion extends beneath the wagon body 27. The members 29 are formed of suflicient strength to withstand the strain of the wagon body and its load and are necessarily -heaviest at their elbow portions, while the portions which extendbeneath the wagon body may be reduced gradually Vtoward their ends, as shown in Fig. 2. The terminals of the hori- Zontal portions of the supports extend beyond the outer edge of the wagon body and are provided with supporting rods 31 having hooks 32 at their upper ends to engage over the upper edge of the outer side of the wagon body, as shown in Fig. 2. By this means the supports are firmly coupled to the wagon body. The portions of the intermediate members 30 which are located between the vertical portions of the supporting member are each formed with a curved recess 33 to engage over a portion of the wheel 25 when the device is elevated, as hereafter explained.

Anti-friction pulleys 34 are mounted upon the supporting members and bear against the outer faces of the plates 21. The wood core 30 of each of the supporting devices is cut out to form a cavity and a holding bolt 35 extends through a vpair of the members 29 and likewise through the cavity. A U-shaped member 36 is arranged to operate between each adjacent pair of the plates 21 and provided with bearing pulleys 37 at their inner ends to engage the inner faces of the plates. Attached to each of the members 36 at its bend is a rod having a hook 38 at the lower end to engage the bolt 35 and with an eye 39 at the upper end.

Mounted for rotation through the frame members 15 is a shaft 40, the shaft being supported by suitable bearings 41 attached to the frame members 15. Mounted upon the shaft 40 between each pair of the frame members 15 is a relatively small winding drum 42, and connected to each of the winding drums is a section of chain, indicated at 43, and preferably connected to a cable 44 which extends over the wheel 25 and within the grooves of the same and is coupled at the other end to the eye 39. If preferred the chain 43 may be extended over the wheel 25 and coupled to the eye and the cable 44 l dispensed with.

Mounted upon the ground at a suitable distance from the crib is a supporting frame, indicated as a whole at 45, and mounted for rotation within this frame is a short shaft 46 coupled at 47 to the adjacent end of the shaft 40, the coupling 47 being preferably of the universal character.

Mounted upon the shaft 46 within the frame 45 is a relatively large winding drum 48 uponwhich a cable 49 is wound and attached to the drum at one end and provided with means such as a hook 50 at the other end to receive the double tree of a team of horses. Located upon the ground adjacent to the front side of the crib is -a channeled wheel guide member 51 in which the wheels, one of which is indicated at 52, at one side of the vehicle run when the wagon is disposed in position adjacent to the crib. It will be notedv by reference-to Fig. 2 that the wheel 52 is disposed internally of the lower inclined portions 19 of the members 18, and that the box 27 is located externally of the plate portions 21. This is the position in which the vehicle must be placed when the load is to be dumped, and by providing the guide 51 this location of the vehicle is rendered certain and easy of accomplishment.

Located between the receiving portion of the crib and the roof 13 are stop members 53 to limit the movement ofthe body 27 after the latter has been elevated into dumping position, as indicated by dotted lines in F ig. 2. The holding members are preferably attached to the body of the wagon and remain thereon so long as the wagon is used in connection with the hoisting apparatus, and where a plurality of wagons are used each will preferably be provided with a set of the supporting members. The supporting members may be attached to the wagon body at any desired points but preferably one will be attached just at the rear of the forward bolster and the other near the rear la@ hicle between the members 18 and 15 and the body 27 externally of the members 18 and the plates 21. The cables 44 are then connected by their hooks 38 to the bolts 35 with the" anti-friction wheels 37 in position against the rear inner faces of the projecting por-- tions of the members 21. The cable 49 being wound a suitable number of times around the drum 48, the team of horses is unhitched from the vehicle and hitched to the hook 50 and when the team is moved away from the drum 48 the cable will rotate the drum and the shafts 46-40 and wind the cables 44 upon the drums 42 and elevate the body 27 with its load until it assumes the position shown by dotted lines in Fig. 2, the sockets 83 engaging over the upper portions of the wheels 25, and the members 53 limiting the movement of the body 27 in one direction. This position of the body will cause the load to be dumped into the crib, and when this is accomplished a slight pull upon a cord or line 54, which is attached to the body 27, will cause the latter to be moved outwardly and downwardly, and then by applying a holding force upon the drum 48 the body 27 can be returned to its position upon the holsters of the running gear of the wagon, as will be obvious. The body may be eased down into its former position by the driver applying a slight outward strain upon the cable 49 which thus serves as a brake to control the return movement of the body.

The improved device is simple in construction, can be inexpensively manufactured and applied without material structural change to cribs of various sizes and to cribs designed to contain various products or substances.

Having thus described the invention, what is claimed as new is 1. In an apparatus of the class described, vertical guides, a cable pulley extending above the upper line of said guides, a supporting device movable over said guides and over said pulley, a carrier device movably engaging said guides and coupled to said supporting device, a cable connected to said carrier device and bearing over said pulley, and means for applying strain to'said cable, to cause said supporting device to travel over said guides and be overturned over said pulley.
